It seems that you return the wrong object somewhere :) Could you commit your code somewhere so I can have a look ?

I started to use Spec, i love nested layouts and so on. But i've got a little problem. I'm creating a Window with 14 TextInputFieldModel and 14 ButtonModel and, to avoid the definition of 28 different instance variables (obviously), i created two arrays which contain the ButtonModel and the TextInputFieldModel that i need. ^ SpecLayout composed newColumn: [ :columnTeam | 1 to: 14 do:[:i| columnTeam newRow: [ :rowPlayer | rowPlayer add: (textPlayer at:i) ; add:#captainButton; add: (buttonStartingEleven at:i). ]. ..... This is what i did in the defaultSpec of my Player class. captainButton is a RadioButton defined in self instantiateModels: in initializeWidgets, while textPlayer and buttonStartingEleven are the arrays of above.Theoretically the idea is great, while in practice it doesn't work. It give me the following message: TextInputFieldModel>>layoutFrame: Help me please!

Hi, Very easy to do. Have a look at http://book.seaside.st You can also load my configuration from http://www.smalltalkhub.com/#!/~philippeback/Hackathon/source This will load the HOWebStack properly, and an app I did for an hackathon. This will give you a sample to work from. There are a bunch of packages in there, get ready for quite a load. If you have issues with this tell me, I'll put a pre made image on my web server for you.

I dont know how Seaside works exactly but yes you can generate dynamically hmtl pages. I have only used Amber that also works with Pharo and it has objects to generate html dynamically.

Re: [Pharo-users] NativeBoost Questions while wrapping FMOD

Igor Stasenko wrote >> The better way is to subclass from NBExternalObject then > which made exactly for such purposes, by holding an opaque handle to > something (you don't care what is inside), and simplifies a lot of things. I made "NBExternalObject subclass: #FMOD_SYSTEM". I then tried to use it via: system := FMOD_SYSTEM new. err := self System_CreateNBExternalObject: system. With callout: ^ self nbCall: #(FMOD_RESULT FMOD_System_Create(NBExternalObject system)). For the argument type in the signature, for good measure I tried: 1. NBExternalObject 2. FMOD_SYSTEM 3. NBExternalAddress All three with zero, one, and two *'s after. The only one that didn't report some variety of "An instance of Xyz expected" was "FMOD_System_Create(FMOD_SYSTEM system)" for which the library returns an invalid argument error code. btw if anyone wants to play with it: 1. Gofer it smalltalkhubUser: 'SeanDeNigris' project: 'FMOD'; package: 'FMOD'; load. 2. Download the FMOD library for your platform: - windows - http://www.fmod.org/download/fmodstudio/api/Win/fmodstudioapi10208win-insta… - Mac - http://www.fmod.org/download/fmodstudio/api/Mac/fmodstudioapi10208mac-insta… 3. Copy the library to "FileLocator imageDirectory / 'FMOD Programmers API/api/lowlevel/lib/libfmod.dylib'" The working example is: | sound | sound := FmodSound fromFile: '/path/to/file.mp3' asFileReference. [ sound play ] fork. The broken one described above is: "FMOD exampleNBExternalObject." ----- Cheers, Sean -- View this message in context: http://forum.world.st/NativeBoost-Questions-while-wrapping-FMOD-tp4724116p4… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
